Description
Within the National Surface Water Quality Monitoring Programme (NAWA), water quality is recorded jointly by the federal and cantonal authorities at around 100 monitoring stations. The numerical requirement of 4 mg/l is used for the assessment in this data set. Dissolved Organic Carbon (DOC) can be an indicator of anthropogenic water pollution. The DOC consists of both naturally present and man-made components. The Waters Protection Ordinance specifies a numerical requirement range for DOC of 1 to 4 mg/l C. The chemical water status is assessed on the basis of the DOC concentration by the “Physicochemical Water Quality, Nutrients” method in the Modular Stepwise Procedure (www.modul-stufen-konzept.ch).
